                This chapter describes methods that can be used to manage
                mutexes within DB. Many of the methods described here
                are used to configure DB's internal mutex system.
                However, a series of APIs are available for use as a
                general-purpose, cross platform mutex management system.
                These methods can be used independently of DB's main
                purpose, which is as a high-end data management engine.
